SHARPENING DEVICE.

Specification of Letters Patent.

Patented April 20, 1909.

Application filed August 25, 1908. Serial No. 450,192.

To all whom it may concern:

Be it known that 1, Moses L. Hawns, a citizen of the United States, andresiding at New York, in the county ol New York and State of New York,have invented certain new and useful Improvements in Sharpening Devices,of which the following is specifioation, such as will enable thoseskilled in the art to which it appertains to make and use the same.

This invention relates to sharpening devices, and the object thereof isto provide an improved device of this class designed for use insharpening knives or various kinds and classes, also for sharpeningscissors, cleavers and like devices, and which may also be used forsharpening skates; and with this and other objects in view the inventionconsists in a device of the class specified constructed as hereinafterdescribed and claimed.

The invention is fully disclosed in the following specification, ofwhich the accompanying drawing forms a part, in which the separate partsor my improvement are designated by suitable reference characters ineach of the views, and in which Figure 1 is a side view of my improvedsharpening device, Fi 2 a view similar to Fig. l but showing theopposite side and a slight modification, and showing one of the parts ofFig. 1 in a different position, Fig. 3 a transverse section on the line33 of Fig. 1, Fig. 4 a side view of a cutter bar which forms a part ofmy improved sharpening device, Fig. 5 a view of the cutter bar shown inFig. 4 and looking in the direction of the arrow (r, and, Fig. 6 asection on the line 6 -6 of Fig. 2.

My improved sharpening device involves the employment of two spring sidearms a which are preferably inwardly curved as shown in Fig. 1, andwhich are set inwardly as shown at a to form a handle member a composedof two parts ax connected. at one end by a loop 0?, ll of said partsbeing prelerably composed of a spring metal rod bent first to form theloop a then the handle members a? and then the spring arms a.

Mounted on the spring arms a is a plate I) provided with keepers I)through which said spring arms pass, and said plate may be adjusted onsaid arms, ll desired, into ditlerent positions, or said plate may bepermanently secured to said arms.

The plate I) is provided centrally with two transverse slots or openings b forming transverse strips b three of which are preferably employed,and the central strip b is bent laterally in one direction and the otherstrips 1) laterally in the opposite direction to form keepers Z) asshown in Fig. 3, and these keepers b are adapted to receive a lile orcutter bar a which is passed therethrough longitudinally of the plate b.

The tile or cutter bar 0 is preferably triangular in form in crosssection, and the keepers If are similarly formed, and the plate I) ispreferably bent laterally longitudinally and centrally thereof, and awedge d is driven through the central keeper If Ol the p ate 1) so as tobear on the bar 0 and securely hold it in place, and the object ofbending the plate 1) laterally and longitudinally is to bring the wedge6/ outside of the plane of the keepers b so that said wedge may beconveniently driven into position or driven out 01' position.

The inner end of the plate I) is provided with a longitudinal recess 6,the side walls of which are curved to form segmental edges c at theopposite sides of the inner end of the bar 0, and the outer end of saidplate is provided with a longitudinal recess f the corners l of thewalls of which are rounded to form l l 1, l l l l l segmental edges f 2which are more abrupt in their curve than the edges 0 of the recess a atthe outer end of the bar c.

Vthen the hereinbeiore described parts are assembled as shown in thedrawing the inner end of the plate I) and the inner end 0 of the plate 0is used for sharpening knife blades of any kin d or class, and the edgesof the blades are inserted at cc on either side of the bar 0, and theblades are moved back and forth so that the edges of the bar 0 will formthe desired edge on said blades.

The edgesf at the opposite or outer end of the plate I) and thecorresponding part of the bar a are used for the purpose of sharpeningthe blades of scissors,'cleavers, choppers and like instruments, theoperation being the same as that above described.

The outer end of the bar 0 is beveled as shown at c to form an ecge c,and by moving said bar into the position shown in Fig. 2 the runner ofthe skate may be inserted into the recess f and drawn across the end ofthe bar 0 and a proper edge may be formed on said runner as will bereadily understood. If the face of the skate runner is plain the edge 0"will be plain or straight, but if said face is grooved or concave theedge 0' of the bar 0 may be similarly formed.

1 also provide means whereby my imav l.

proved sharpening device may be used as a can opener, and in order to dothis I place on the transverse part of the loop a of the handle portionof the device a sleeve 9 having a laterally and outwardly curved prong gand I also mount on the handle portion of the device or the parts athereof a slide h provided with a pointed or triangular blade 7L2 whichprojects outwardly in the same direction as the prong g and by insertingthe prong g through the center of the head of a can the slide it may beadjusted so that the blade k may be passed through the outer edgeportion of said head, and then by turning the device by grasping thearms a the head of the can may be easily out out as will be readilyunderstood.

My improved sharpening device is simple in construction, comparativelyinexpensive and perfectly adapted to accomplish the va rious results forwhich it is intended; and changes in and modifications of theconstruction herein described may be made, Within the scope of theappended claims, without departing from the spirit of my invention orsacrificing its advantages.

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent, is

1. A sharpening device comprising a handle portion provided withprojecting arms,

erases a plate secured to said arms and provided j centrally andlongitudinally thereof with kee ers which project in oppositedirections, l a fill; or cutter bar passed through said keepit therein,said opposite ends j'Wli/ll longitudinal recesses forming curved jedges, the curve of the edges at one end be- I l l ers, and means forsecuring .plate being provided at lts ing more abrupt than those at theopposite end.

2. A sharpening device comprising a handle portion provided withprojecting arms, a plate secured to said arms and provided at itsopposite ends with longitudinal recesses, said plate also providedcentrally and longi- J 1 i tudlnally thereof with transversely arrangedi keepers which project outwardly in opposite directions, a cutter barinserted into said keepers, and means for securing it therein, jStIlClcutter bar being beveled at the end i forming a cutting edge thereonadapted to j sharpen the runners of lce skates.

In testimony that I claim the foregoing as my invention I have signed myname .in j presence of the subscribing witnesses this j 22nd day ofAugust, 1908. MOSES L. HAWKS. Witnesses: A. R. APPLEMAN, W. W. OANFIELD.
